  • how to add audio to existing video using FFMPEG at specific time ?

    29 juin 2023, par Yanshof

    I have video file (.avi) that contain video of 10 minutes. 
I also have audio file (.wav) that contain 1 minute of sound.

    



    I need to add the audio to the exist video but the audio need to start at after one minute of the video

    



    How to do it ?

    



    ( prefer using ffmpeg if its possible )

    



    try already this query ( 30 seconds delay )

    



    -i video.avi -i audio.wav -filter_complex \"[1]adelay=30000|30000[aud];[0][aud]amix\" - c:v copy out.avi"

  • how to add audio to exist video using FFMPEG at specific time ?

    10 janvier 2018, par Yanshof

    I have video file (.avi) that contain video of 10 minutes.
    I also have audio file (.wav) that contain 1 minute of sound.

    I need to add the audio to the exist video but the audio need to start at after one minute of the video

    How to do it ?

    ( prefer using ffmpeg if its possible )

    try already this query ( 30 seconds deley )

    -i video.avi -i audio.wav -filter_complex \"[1]adelay=30000|30000[aud] ;[0][aud]amix\" - c:v copy out.avi"

    attached the log of ffmpeg when trying to marge more then one wav

  • ffmpeg fails to copy correct duration

    2 février 2016, par guneykayim

    I want to trim a video with the following command :

    ffmpeg.exe -i in.mp4 -ss 76 -t 10 -c copy -an out.mp4

    which exactly means, copy 10 seconds after 76 seconds, and don’t copy audio. However out.mp4 is 5 seconds length.

    This is ffmpeg console output :

    ffmpeg.exe -i in.mp4 -ss 76 -t 10 -c copy -an out.mp4

video:1499kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 0.194616%

    When I analyze this console output I see this inconsistency. It says output time is 9.96 seconds. On the other hand it says frame is 143, so from the latter information I can calculate duration by frame/fps which is 143/23.98=5.96.

    Another strange behaviour with this copy command is when I change the start time to something else output video length is varying between 5-10 seconds depending on the start time.

    What might be the problem causing these unexpected behaviours ?
